First test flight with this aircraft - 8 minutes of flying time consumed 57% of the battery capacity. The power comes from a 35 kG LIPO battery pack, and it's estimated to have 14 minutes total flying time or 11 minutes to 80% depth of discharge. He's not wearing a helmet to feel the freedom thing.

It kicks up quite a bit of "wind" while flying - notice what happens to the plants.

Since this is an initial test flight, he's taking it easy ("don't fly higher than you want to fall"). Certain control system limits were set conservatively and he may loosen those limits for future flights.
